Abstract

The problem addressed by the invention was to provide a foam regulator system containing silicone and/or paraffin and bis-fatty acid amide which would have a low viscosity, which could be handled at low temperatures and which would have a low percentage content of non-foam-regulating ingredients. This problem was largely solved by an aqueous foam regulator emulsion containing 16% by weight to 70% by weight of active foam regulator based on paraffin wax and/or silicone oil, 2% by weight to 15% by weight of nonionic and/or anionic emulsifier and no more than 80% by weight of water. The foam regulator emulsion is preferably used for the production of partiulate foam regulator granules for use in detergents.
